MariaDB - how to populate database at startup

Hi all,

I have a question - how would one go at it to populate a MariaDB database with a number of tables each time a pod gets deployed (I'm running this on OpenShift)?

The idea is that I have a script that checks if a certain table already exists and, if not, it should create a number of tables.

What would be the best approach to getting that bash script executed so I'm sure that, whenever a pod is started, I have the tables needed for the application to run correctly?

A big thank you in advance for any ideas / suggestions!

Bernard.
